: The aim of the present study was to evaluate the normative need for orthodontic treatment and the perception of such need among students aged 11-14 years.
: A cross-sectional study was conducted with a sample of 346 students, randomly selected from public and private schools. The Dental Aesthetic Index (DAI) was used to evaluate the normative need for orthodontic treatment (NNOT). The perceived need for treatment among students was assessed by a previously validated questionnaire. Data was analyzed by Pearson's Chi-squared test (α = 5%).
: The prevalence of malocclusion and NNOT was 65.6%. Of the sample, 73.7% felt they needed treatment, 66.2% wanted orthodontic treatment and 62.7% were satisfied with their dental aesthetics. A statistically significant association was observed between NNOT and the perception of the need for treatment among the students (p < 0.001).
: The present study demonstrated a high prevalence of malocclusion, which was reflected in the high normative need for orthodontic treatment. The opinion of patients regarding their expectations of orthodontic treatment should be valued. The students perceived a need for orthodontic treatment.
本研究旨在评估11至14岁学生对正畸治疗的规范需求以及对这种需求的认知。
对从公立和私立学校随机抽取的346名学生进行横断面研究。使用牙齿美学指数（DAI）评估正畸治疗的规范需求（NNOT）。通过先前验证的问卷评估学生对治疗的感知需求。数据采用Pearson卡方检验进行分析（α = 5%）。
错牙合畸形和规范需求的患病率为65.6%。在样本中，73.7%的人认为他们需要治疗，66.2%的人希望接受正畸治疗，62.7%的人对自己的牙齿美观感到满意。在规范需求与学生对治疗需求的认知之间观察到统计学上的显著关联（p < 0.001）。
本研究表明错牙合畸形的患病率很高，这反映在正畸治疗的高规范需求上。应重视患者对正畸治疗期望的意见。学生们认为有正畸治疗的需求。
